Reasons for trip to take place
Types of volcanoes in Hawaii
Three basic types of volcanoes are recognized by geologists.
- Shield, with its broad, gently sloping form, made of once fluid lavas. Mauna Loa is the type example.
- Cinder cones, steep sided (25-33 degrees), made of fragments of lava that were spit out of the volcano. Most of these cones are small (100's of meter across, although some get large, several kms). Mauna Kea has some of these cones as does Waianae.
- Composite or strato-volcanoes are composed of once pasty lavas and layers of lava fragments (from explosive eruptions). It has gentle to moderate slopes on flanks and is steep near the summit. Usually smaller than shields but larger than cinder cones. Some of these volcanoes, like Crater Lake volcano, have cinder cones on it.

How the Volcanoes on Hawaii were formed ?
The Hawaiian Volcanoes were produced by the Hawaiian hot spot,which is presently under the big island of Hawaii.
Where Hawaii is located
Hawaii is located about 2,500 miles west-southwest of the mainland U.S.A., about a five-hour flight from the California coast.The state of Hawaii is made up of a group of volcanic islands. It is located in the central Pacific Ocean. The eight major islands from west to east are: Niihau, Kauai, Oahu, Molokai, Lanai, Kahoolawe, Maui and Hawaii. Mauna Loa and Kilauea on the island of Hawaii are still active volcanoes.
